Raj wakes up in the morning and notices that his digital clock reads 07 2(A)5(B).After noon, he looks at the clock again. what is the probality that I) The number in column A is 4?
ii) The number in column B is an 8?
iii) The number in column A is less than 6?
iv) The number in column B is greater than 5?

i.  

ii.  

iii.  

iv.  

Step-by-step explanation:

Given

Time: 07 2(A) 5(B)

Calculating (a)

First, we need to list out the possible sample space, S of A

Probability of A being a 4 is the number of occurrence of 4 divided by the number of sample space

Hence;

Calculating (b)

First, we need to list out the possible sample space, S of B

Probability of B being a 8 is the number of occurrence of 8 divided by the number of sample space

Hence;

Calculating (c)

Using the sample space in (a)

Probability of A being less than 6 is the number of occurrence of less than 6 divided by the number of sample space

Hence;

Calculating (d)

Using the sample space in (b)

Probability of B being greater than 5 is the number of occurrence of greater than 5 divided by the number of sample space

Hence;

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
